Topband: W8ji ATR-10 design 160M?

[Jim GM]

What is the real or best guess what value this inductor has? This is what I
am using.

Edge wound coil is 1/2 inch wide, 1/32 inch thick stock, coil is 2 1/2
inches long,15 turns, 4.5” ID, 5.5” OD

transmit tap is at 9 turns, 6 turns remain going to antenna. Inductance
calculations were found here

http://www.66pacific.com/calculators/coil_calc.aspx<%22http://www.66pacific.com/calculators/coil>
Total inductance is 29.6uH, 9 turns = 12.7uH, 6 turns = 6.7 uH, 6 turns =
7.9 feet.

If you wound a coil with 1/8 inch or 1/4 inch copper tubing , is there any
online calculator that can give you a good answer on its value?
